Hi Michael,
Thank you for your reply, but I'm on a PC / Linux Ubuntu 14.10 with
Tkinter/Tk version 8.6 for Python3, standard installation, no specific
tuning.
I'm working this way to fit as much as possible with customers' machines
who'd use my apps, generally without making any changes to their
platform pre-installed packages.
I'm not looking for a bug fix on my own, I'd like to acknowledge
Tkinter's dev team that this bug exists, hoping that in some late days
it will be fixed everywhere for everybody. :)
I thought tkinter-discuss was the best place for this.
I don't know if there is a bugtracker for Tkinter somewhere.
I don't even know if Tkinter is still in development, in fact.
Is it?
Regards.

Subject: [Tkinter-discuss] Weird bug in input widgets?
Message-ID: <54cc9036.5060...@laposte.net>

Hi all,
While working on my latest software (tkScenarist on GitHub), I
encountered a really weird issue: once cleared, input widgets such as
Text, Entry, ttk.Entry do *NOT* accept composite-accented letters
(french ?, ?, etc) any more.
So, to get sure, I made the following test code:
[CODE]
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from tkinter import *
def clear_all (event=None):
# clear stringvars
for svar in cvars:
svar.set("")
# end for
# clear text widgets
for wtext in texts:
wtext.delete("1.0", END)
# end for
# end def
def test (nb_of_widgets):
global root, cvars, texts
root = Tk()
root.title("test #{}".format(nb_of_widgets))
cvars = list()
for n in range(nb_of_widgets):
svar = StringVar()
cvars.append(svar)
Entry(root, textvariable=svar).pack()
# end for
texts = list()
for n in range(nb_of_widgets):
wtext = Text(root, height=2, width=20)
wtext.pack()
texts.append(wtext)
# end for
Button(root, text="Clear all", command=clear_all).pack(side=LEFT)
Button(root, text="Quit", command=root.destroy).pack(side=RIGHT)
# events main loop
root.mainloop()
# end def
if __name__ == "__main__":
# launch test series
for n in range(1, 4):
test(n)
# end for
# end if
[/CODE]
Detailed description of the issue:
* French keyboards are arranged in such a way that you must compose
accented letters as ? (e circumflex) or ? (e diaeresis) by pressing
first the '^' key and then the letter to compose with (e.g. a, e, i, o,
u, y) in order to get the final composite-accented letter (?, ?, ?, ?,
and so on);
* when you launch the test script (cited above) and then type, let's
say, the e circumflex letter (?) into the Entry widget and into the Text
widget, respectively:
* the first time, you'll get the right letters inserted into the input
widgets;
* then click on 'Clear all' button and enter once again the same
composite-accented letter into *ALL* the input widgets;
* secund time, only the last pack()-ed input widget will get the right
input, all other widgets will show unaccented letters;
* the test script tries with 1 Entry and 1 Text input widgets, then with
2 input widgets and finally with 3 input widgets;
* each time you get the same issue: only the last pack()-ed input widget
shows the right input letter, all the rest showing unaccented letters.
This issue is quite embarrassing for me as my latest software manages
with movie scenario scriptwriting, which *MUST* be written with correct
accents in French, otherwise all the purpose of the software would collapse.
Is this a known issue?
Thank you for your expert advice.
Regards.

Hi Rapha?l,
I cannot reproduce this behavior here (debian wheezy, Tk-8.5.11), however
I could only test it with a german keyboard layout with X-Composite key or
with dead keys temporarily enabled in xfce. I don't think that should
matter, though, here everything seems to work fine.
I can only guess, but it sounds to me like a platform- and/or Tk-version
specific issue. If you are running OS X and a recent version of Tk it
might or might not have something to do with the bug described here:
http://sourceforge.net/p/tktoolkit/bugs/2722/
resp. with the fix that was supplied for that bug. That is is just a shot
in the dark of course.
Regards
Michael
